1. One can also define a similar curve for dim conditions ( scotopic vision ). 2. Scotopic vision is dominated by retina amacrine cells, specifically all-amacrine cells.3. Photopic vision facilitates excellent color discrimination ability, whereas colors are indiscriminable under scotopic vision . 4. In scotopic vision , people are more sensitive to light which would appear greenish-blue. 5. Scotopic vision occurs at luminance levels of 10 " 3 to 10 " 6 cd / m?6. In most night-time environments, there is enough ambient light at night to prevent true scotopic vision . 7. Central vision is relatively weak in the dark ( scotopic vision ) since cone cells lack sensitivity at low light levels. 8. The sensitivity to light in scotopic vision varies with wavelength, though the perception is essentially black-and-white. 9. Other forms of amacrine cell are likely to play modulatory roles, allowing adjustment of sensitivity for photopic and scotopic vision . 10. Could it have been Purkinje effect or scotopic vision ?-- Shantavira 07 : 01, 12 August 2006 ( UTC)
